Fat Transfer for Patient with Morphea?

My partner had been diagnosed with Morphea, unfortunately it has affected the right cheek area of her face, fortunately this condition has now ceased, however my partner has been left with a loss of tissue in this area, she has been getting collagen boosting fillers. However, these do not appear to be having a lasting effect.We have been advised that a more permanent procedure ie: Fat transfers may be more suitable, can you advise us as to whether or not this is an option and whether or not professionals would be willing to help someone who had been diagnosed with this condition?
